94 deviants said Rarity is an idiot if she genuinely thought the eyepatch would be enough. Twilight even more so for rolling with it (she was still clearly an alicorn... with an eyepatch).
75 deviants said How come no one arrested and sentenced Flim and Flam for all their cons... And why their punishment is only "return bits you earned in a dishonest way" - where is the fine! The actual punishment!?
67 deviants said Even after hundreds of years in limbo, Star Swirl should be smart enough to see through Flim and Flam's con. Also, he should value his reputation and not ruin it to advertise such a school.
62 deviants said Friendship University abbreviates to... FU
39 deviants said Why won't Twilight just release her book with friendship lessons so ponies can learn from it. What is her point? Get students for her school or teach friendship?
26 deviants said Twilight Sparkle and Rarity hate free market.
24 deviants said Rarity is way too generous. She should have used school funds to buy a lot of school stuff... unless she planned to create a manufacture with child labor to make cheap dresses she could sell in her boutiques...
23 deviants said How come no one questioned the practice of paying bits for every single page? And no one shared their copies with others for free or half the price?
22 deviants said Removing every other page from Twilight's manual would make many lessons incoherent or abruptly ending at some point (unless one page = one lesson, but then it's still missing a lot stuff possibly referenced on other pages)
20 deviants said Despite learning about loyalty from Rainbow Dash, so many students were instantly willing to switch schools, once they saw a leaflet.
